NeoTech DAF process consists of super saturation of discharge water from the effluent end of the system tank with air. The super saturated water stream is then mixed with the waste stream and pressurized in pressure tube. A sudden release of pressure from the saturated stream millions of microscopic bubbles form and attach themselves to the contaminants of oil and solids in the wastewater, thereby changing their buoyancy and floating them to the water surface where they can be skimmed and removed from the water. NeoTech also offer a combined chemical pretreatment to improve DAF solids removal efficiencies.

Features :

• The use of chemical flocculants with DAF is based on system efficiency, application contaminant characteristics and cost. Chemical pretreatment often improves DAF solids removal efficiencies. The use of chemical flocculants with DAF is based on system efficiency, application (use of DAF) contaminant characteristics and cost.
• Commonly used chemicals include trivalent metallic salts of iron, such as FeC_I2 or FeSO₄ or aluminum, such as AISO₄. Organic and inorganic polymers (cationic or anionic) are often used to enhance the flotation process. The most commonly used inorganic polymers are the polyacrylamides.
• Attachment of most of the bubbles to solid particles can be effected through surface energies while others are trapped by the solids or by hydrous oxide flocs as the floc spreads out in the water column. Colloidal solids are normally too small to allow formation of sufficient air-particle bonding.
• They must first be coagulated by a chemical such as the aluminum or iron compounds mentioned above and then absorbed by the hydrous metal oxide floc generated by these compounds. Frequently the coagulant is required in combination with the flocculant.

Automatic micro-filtration equipment is used in solid-liquid separation in aquaculture water/water/sewage system.RDF is a reliable mechanical filtration method, it can separate solids, suspended substances(including feces, food waste and other organic water) over 30μm from water.

WAVE dewatering press is a solid- liquid separator machine with self-cleaning function by slits opposite continuous rotation, no vibration and noises. 

Plate-frame filter press is a kind of intermittent solid-liquid separation equipment, which is composed of filter plate and filter frame to form a filter chamber. Under the pressure of the feed pump, the material liquid is sent to each filter chamber and the solid and liquid are separated by the filter medium. The equipment is widely used in chemical industry, dyestuff, petroleum, ceramics, pharmaceutical, sugar, starch, paint, metallurgy and sewage treatment, etc. It has the advantages of good separation effect, wide application range, simple operation and low investment, etc. In particular, the separation of sticky and fine materials has in comparable advantages. 

Advantages: Plate-and-frame filter press is a mature dewatering equipment with simple structure, easy operation, stable, flexible selection of filter area, less area per unit filtration area, large filter driving force, and low moisture of filter cake. Strong adaptability to materials, suitable for all kinds of sludge. 

Intro: The screw press is a device that uses physical extrusion to dewater the device. The device includes driven System, feed box, spiral auger, screen, pneumatic material blocking device, sump, rack, etc. The material enters into the equipment from the feeding box and is subjected to progressive pressure extrusion under the conveying of the spiral auger. Excess water is discharged from the liquid outlet through the screen, and the moisture-removing material is continuously transported by the spiral auger. The top opening and blocking device is discharged from the discharge port by the discharge port. It is truly low energy consumption, high output, low moisture, and secondary circulation for material to save a lot of processing costs. 

Working principle: The dewatering process of the screw press dewatering machine is divided into two stages. The first stage uses the screw auger to dehydrate. The spiral auger has three sections: the transmission section, the compression section and the discharge section, and the transmission space become smaller gradually to press the materials stronger and make the material extruded water. The second stage uses a material-blocking device to dewater. When the material enters into the discharge section of spiral auger, the spiral auger applies axial thrust to the material to push it out of the discharge port, while the pressure device is pressurized by the pneumatic device which applies a reverse force to the material to be pushed out, thereby forming a pressing force to the material to realize the dehydration. 

Conventional clarification equipment requires 10 times more physical area to even begin to approach the same settling capacity of a Neotech Lamella Gravity Settler. This means faster settling in one-tenth space because the effective gravity settling area of the inclined plate design equals each plate are projected on a horizontal surface. Up to ten square feet of settling area becomes available for each square foot of physical area occupied by the unit. Loading rates normally used for the design of conventional settlers can be applied to the sizing of a Lamella Settler by substitution projected area for the surface settling area of a conventional clarifier.
 
The compact design minimizes hydraulic disturbances caused by wind or temperature changes. Balanced flow distribution ensures equal flow to each plate and across the plate surface area preventing short-circuiting.
 
Units and plate packs arrive at the job site factory assembled which reduces installation time and lowers installed costs. Minimal moving parts mean low maintenance costs.
 
How it Works:
Influent enters the lamella system and flows downward through the inlet chamber in the center of the unit and enters the plates through side – entry plate slots. The countercurrent design, unlike typical bottom feed designs, reduces the risk of disturbing previously settled solids. As the liquid flows upward, the solids settle on the inclined, parallel plates and sludge into the sludge hopper at the bottom. Further thickening of the sludge is achieved in the hopper due to compression in the quiescent zone achieved by the side feed design.
 
The clarified liquid leaves the plate assembly through orifices or weirs at the top and is distributed into the collection channels leading to the clarified water outlet. This creates a pressure drop across the collection channels which ensure uniform flow distribution across the plates in order to utilize the full area for settling.

The Coalescing Plate Interceptor employs a series of plate packs inclined at opposite angles in close proximity; the most effective technique for increasing setting area per unit volume. As a result, CPI Separators requires far less space than settling tanks. The units can be offered in fully certified pressure vessels, or atmospheric tanks. Process Technology Waste water enters the inlet nozzle into an enlarged coalescing section. This coalescing section is where heavier solids and sludge settle out of the waste water to the bottom of the vessel where it is discharged through the clean out nozzle. Waste water then flows through the perforated distribution baffle plate. After it is evenly dispersed, it flows down through the plate pack where oil rises to the top of the corrugations and coalesces with other oil droplets. The large oil droplets rise up through the plate pack to the oil/water interface. Coalesced oil will flow over an internally adjustable oil weir and is removed through the oil outlet nozzle. Light solids and sludge separation is simultaneously accomplished within the pack by settling to the bottom of the corrugations where solids are directed to the sludge drain. The flow out of the plate pack travels upward and spills over a fixed water weir, then exits the vessel through the water outlet nozzle for further downstream treatment or disposal. Our CPI Separators effectively remove oil droplets of 50 microns or larger, depending on fluid properties.

 The solid phase particle size 0.005 15 mm, 1 40% concentration, temperature < 100 of all kinds of slurry solid phase dehydration, clear separation of liquid phase, sizing, etc. Especially suitable for regeneration of filter cloth have difficulty bigger suspending liquid separation and concentration, particle size change. 

NeoSkim After a long period of testing, the ideal design was developed. A complete new design which ensures a high efficiency. The NeoSkim Belt Type Oil Skimmer is a dependable and effective means of removing oil from water and wastewater base solutions. Often, skimming by itself will reduce oil to an acceptable level of water purity. Depending on the characteristics of the liquid, it is possible for NeoSkim alone to reduce oil content to less than five parts per million in water. The unit can be used as a pretreatment before filtration, and in conjunction with coalescing systems.

Features :

• Require Small Area Easy Mounting High Temperature Capability Custom Design Fast Cleaning Minimum Maintenance How it works? The NeoSkim Model utilizes a continuous belt and wiper to remove up to 150 liters of oil per hour from the fluid surface.
• The belt, operating on a motor and pulley system, runs through contaminated liquid to pick up oil from the surface. After traveling over the head pulley, the belt passes through tandem wiper blades where oil is scraped off both sides of the belt and discharged.
• The tail pulley has flanges which allow it to roll freely on the inside of the belt without becoming dislodged. It requires no bearings and does not need to be fastened to the tank. If turbulent conditions exist, an optional tether and cage assembly prevents the tail pulley from being dislodged.
• Oil skimming makes use of the differences in specific gravity and surface tension between oil and water. These physical characteristics allow the belt to attract oil and other hydrocarbon liquids from the surface of the fluid.
• The NeoSkim can be used in tanks with depths as shallow as one foot, or as deep as 100 feet.
