The "Mini Batch" chemical/physical treatment process has been designed in particular for the separation of very fine and light suspended particles from industrial process water. Materials like suspended dyes and particles from the processing of concrete, glass and natural stone are pre-treated and separated in a very efficient process. The process used for these specific applications accommodates flocculation, sedimentation of flocculated materials and concentration of the settled solids. The quality of the treated process water allows recycling as "clean" process water or discharge in a sewer or surface water.
The polluted process water is pumped into a Poly Ethylene tank, which serves as a buffer/equalisation tank, in which a mixer is mounted. When the tank volume exceeds a preset level the mixer starts and flocculation of, often colloidal, suspended materials is achieved by dosing flocculant into the feed pipe of the tank.
After a preset mixing time the flocculated water is pumped by means of a submersible pump into the settling tank. This tank is executed with a conical base to enhance settling and sludge thickening. During the settling process a clear water layer, supernatant, is formed and after finalising the preset settling period, this clear water layer is discharged via a pneumatic operated valve.
The pre-dewatered sludge is discharged from the settling tank to the "Big Bag" thickener through a pneumatic operated valve. Two (2) to four (4) batches can be treated hourly, dependent on the type of solids and concentration in the raw influent.
Rake screens are applied for separating solids from process water or wastewater.
Curved screens are applied for separating solids from process and wastewater.
The rotary drum screens are characterised by maximum separation efficiency against low running- and maintenance costs.
We have developed a special dewatering press to dewater coarse and fiber-like materials. This press combines the advantages of the shaftless auger with the dewatering characteristics of wegde wire (as applied in e.g. bow- and drum screens).
We have developed a special feather press to dewater coarse and fiber-like materials. This press combines the advantages of the shaftless auger with the dewatering characteristics of wegde wire (as applied in e.g. bow- and drum screens).
The RPF flocculator is characterised by the plug flow principle. The retention time is almost uniform and the mixing energy in the cross-section of the pipe is constant. In this way, all particles in the flocculator are subjected to a completely equal mixing energy.
The KWF flotation units are extremely compact and make use of plate pack technology for removing suspended solids, oil, fat, grease and other dispersed and/or flocculated materials with micro flotation.
The KCL flotation units are designed to treat large wastewater flows for the removal of suspended solids, oil, fat, grease and other dispersed and/or flocculated materials with micro flotation.
The GPL units have been designed for wastewater with COD contents of 10 000 mg/l and higher. In the same system, suspended solids, fat, oil, grease and other dispersed and/or flocculated materials are removed.
The complete design of the GWL systems is based on elimination of hydraulic disturbances, resulting in a complete stable and laminar flow at all cross sections of the system.
The WWL units have been designed for wastewater with COD contents of 10 000 mg/l and higher. In the same system, suspended solids, fat, oil, grease and other dispersed and/or flocculated materials are removed, as well as settled materials.
The cross flow separator systems permits very effective separation of settling materials like sand, fibres, etc. Raw water, containing suspended solids passes in horizontal direction between the closely spaced plates in the plate pack.
Separation of oil and suspended solids from refinery and allied water effluents by means of "plate pack" modules, working by gravity separation between spaced corrugated plates, is proven technology.
The wastewater (after primary treatment) is pumped into the aeration basin, which is filled with an activated sludge/water mixture.
Our biological wastewater treatment system, type BIOCON is designed to treat wastewater capacities in standard systems from 50 to 500 population equivalent.
The Trennbag system for wastewater treatment enables you to free the cooling water, which is used for sawing and polishing, from sediment without any problem.
We have developed a range of efficient separators to remove fast settling materials, like sand, from water. Based on the difference in specific gravity between the water and the settling materials, predictable and maximum separation efficiencies are achieved.
The flume system is developed for instantly removal of all vegetable cuttings and waste of the production departments concerned in the fresh cut industry. This ingenious and robust transport system is installed in the factory floor underneath the production lines.
The washing area is made with slopes in two directions. This double slope makes the washing of the livestock trucks easier. The cleaning itself is done with medium high water pressure and a relatively high amount of water.
The PFL flocculator is a tubular reactor where chemicals for coagulation, neutralization and flocculation are added to the wastewater under controlled circumstances.
The FBR is a compact built continuous biological wastewater treatment system. After pre-treatment (screening), the wastewater flows into a reactor tank with aerator.
In a Membrane Bio Reactor a combination of a biological treatment process and a membrane filtration unit is used. The biological treatment process can be aerobe, anoxic or anaerobe.
The CPF and PWF units are designed to get a complete laminar flow through the unit in combination with a small footprint.
The flotation unit consists of a flotation tank equipped with the special "low friction" inlet compartment, an aeration system and a sedimentation discharge system with sludge compartment.
The K-Pack flotation units are designed to remove solids, oil, grease and/or flocs from the wastewater which do not have sufficient buoyancy to float.
The PCS and CPS cross-flow separators are designed to separate settling parts like fibers, starch and sand from the wastewater.
