The TBR™ is an advanced MBBR™ biofilm technology is based on specially designed plastic biofilm carriers or biocarriers that are suspended and in continuous movement within a tank or reactor of specified volume. The design of associated aerators, grids, sieves, spray nozzles and other integral parts to the reactor is also of great importance in making up the system as a whole, which is what Wock Oliver is marketing . A bio catalyst is used in VOK bio media which is specific to various industrial effulents. This makes TBR™ far more advanced than ordinary EEC / Anox Kaldnes type systems. The industrial and municipal wastewater is led to the MBBR™ treatment reactor where biofilm, growing within the internal structures of the biocarriers, degrade the pollutants. These pollutants that need to be removed in order to treat the wastewater are food or substrate for growth of the biofilm. The biocarrier design is critical due to requirements for good mass transfer of substrate and oxygen to the microorganisms and there is a continuous R&D in the area of the MBBR™ biofilm technology . Excess biofilm sloughs off the biocarrier in a natural way . Close up of biofilm-chip from biofilm treatment process An aeration grid located at the bottom of the reactor supplies oxygen to the biofilm along with the mixing energy required to keep the biocarriers suspended and completely mix within the reactor. Treated water flows from reactor through a grid or a sieve, which retains the MBBR™ biocarriers in the reactor. Depending on the wastewater, the reactors are may be equipped with special spray nozzles that prevent excessive foam formation.

wock-oliver’s filter presses are used for the purpose of dewatering sludge and slurry produced in wastewater treatment, and chemical and mineral processing. Most wastewater treatment processes will produce sludge or slurry that is commonly disposed as a liquid waste. This sludge or slurry can be dehydrated in an wock-oliver’s filter press via a method called sludge dewatering. By using an wock-oliver’s filter press a reduction of up to 90% sludge volume can be achieved. in most instances the sludge or slurry is conditioned with polyelectrolyte and then dewater in an wock-oliver’s filter press to produce a solid dry filter cake. the filter press has been the focus of manufacturing for many years. We have built a solid reputation for building quality filter presses, clarifiers, sludge dryers, complete waste treatment systems, filter cloths and filter plates plates. Our filter presses have been used in a variety of industries from plating and metal finishing to chemical and food processing to name a few. Wock-oliver filter presses feature heavy duty steel construction with polypro gasketed plates. These filter presses can be manufactured with manual or automatic closures, but always with a hydraulic cylinder for sure, high pressure closing. Wock-oliver filter presses are always expandable for larger future capacity by adding longer sidebars and additional plates. standard filter press features: + air driven hydraulic closing pump with pressure gauge on automatic units + 2 stage hand pump on manual units + heavy duty hydraulic cylinder for opening and closing of press + polypro gasketed recessed plates for leak free operation + air blown manifold piping for air drying filter cakes + air line filter, oiler, regulator and gauge on automatic units. optional features: + sludge dump carts for sludge collecting and dumping + cat-walk platform with raised legs for disposal into drums or our sludge dryer + automatic plate shifter for ease of cleaning + distance piece for future expansion + leg mounted control panel + diaphragm pump for solids feed to the filter press. filter press applications: + dewatering industrial sludge + reclaiming precious metals + processing of pharmaceuticals + product filtration + dewatering hazardous wastes + process waste waters in epa approved treatment systems

Wock-Oliver's DAF , Dissolved air floatation clarifier has been widely used for industrial wastewater treatment. The typical industrial wastes treated by flotation are paper mill backwater, oily wastewater as well effluents from sugar, dairy, textile industries and tanneries. Dissolved air flotation clarifiers or dissolved air flotation units (with 3 - 5 minutes of detention time) can replace sedimentation (with 2 - 3 hours of detention time) for clarification, has been overlooked by environmental engineers for many decades. Modern high rate DAF clarifiers have advanced to such an extent that they could overshadow conventional settling clarifiers in wastewater treatment. DAF hydraulic loading has increased from 1 L/m2.s to 2.5 L/m2.s and for a triple stacked unit to 7.5 L/m2.s. The detention time has decreased from 30 minutes to 3 minutes. Air dissolving is improved and now requires only 10 seconds retention time in the air mixing tube instead of the previous 60 seconds. The smaller size and weight of a modern DAF unit allow for inexpensive construction and flexibility of erection using prefabricated units. The availability of excellent flocculating chemicals gives a high stability of operation and high clarification degree. DAF ADVANTAGES Low capital and operational costs Continuously self-cleaning Totally integrated Minimal maintenance Pre-engineered Stable operation Space saving and low foundation costs High quality clarified water Simple installation Superior performance High chemical efficiency Easily relocatable
ULTRA FILTRATION Ultrafiltration (UF) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. This separation process is used in industry and research for purifying and concentrating macromolecular (103 - 106 Da) solutions, especially protein solutions. Ultrafiltration is not fundamentally different from microfiltration or nanofiltration, except in terms of the size of the molecules it retains. Mostly, ultrafiltration is applied in cross-flow mode and separation in ultrafiltration undergoes concentration polarization. UF membranes typically have pore sizes in the range of 0.01 - 0.10 µm. The smaller the nominal pore size, the higher the removal capability. Advantages + High removal capability for bacteria and most viruses, colloids and silt + Does not introduce any chemicals to the water + Produces no by-products + Does not alter the taste, pH or other properties of the water + Easy and cost-effective to install and maintain without any special training NANO FILTERATION Nano filtration is a pressure driven separation process. It is much the same as reverse osmosis. The key difference is the high degree of removal of monovalent ions, multivalent salts and low molecular weight organics in the reject. Reverse osmosis removes the monovalent ions at 98-99% level at 200 psi. Nano filtration membranes’ removal of monovalent ions varies between 50% to 90% depending on the material and manufacture of the membrane. There is variety of Nano filtration membranes available. Each type is particularly suited to a certain application and may not be acceptable to a different application. APPLICATIONS + Water softening + Food and pharmaceutical applications + Desalination of dyestuffs + Caustic recovery + Color removal + Removal of pesticides from groundwater + Removal of heavy metals from wastewater + Wastewater recycling in laundries + s Nitrates removal
