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. Completely laminar flow conditions are established while the water flows across the plate pack from the inlet to the outlet side. Laminar and stable flow conditions are essential conditions for the effective gravity separation of the water and the suspended contaminants.
Solids move towards the bottoms of the corrugations and slide down the incline of the plate. From there, the separated solids are collected in the sludge compartment at the base of the separator to be transported by a shaftless spiral conveyor and intermittently discharged through a valve. Settled sludge cannot recontaminate the treated water. The solids move perpendicular to the flow of water, eliminating particle re-entrainment completely.
All our separators are custom built with respect to the number of plates in the pack, the length of the plates, the distance between the plates and the plate inclination. The number and the length of plates are determined as a function of the raw water flow rate to be processed in the separator. The distance between the plates is depending on the concentration of solids/sludge in the raw water. The inclination of the plates is set between 45 and 60 degrees, depending on the general nature of the solids (density, viscosity, concentration).
All systems are standard constructed in AISI 304, executed with either a shaftless spiral conveyor or a slanted sludge compartment at the base.
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.
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 "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.
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.
