Solid liquid separation involves the separation of two phases, solid and liquid, from a suspension. Any separation system design must consider all stages of pre-treatment, solids concentration, solids separation and post-treatment. This encompasses a wide range of equipment and processes. Greendex has extensive experience in this area. We offer a range of liquid solid separation equipment to meet our customers’ individual requirements.
Greendex in association with JWC Environmental provides our customers the complete range of grinding and screening equipment which is designed specifically to meet the municipal, commercial and industrial demands.
JWC Environmental has thousands of successful Monster installations around the world in a wide range of applications such as municipal and industrial wastewater, food waste management, healthcare, oil and gas and others.
The patented Muffin Monster® design has established new standards in product performance and reliability due to decades of technical advancements and innovative design improvements. For the municipal wastewater applications, the rugged sewage grinding machines shred most any material capable of disrupting your system.
With over 40,000 installations, the Muffin Monster® sewage grinder has proven itself in the most demanding wastewater solids reduction applications including: pump stations; sludge lines; septage receiving stations; prisons and more.
In today’s modern wastewater treatment plants, meeting high standards in effluent quality, cost efficiency and odor control is a must. Monster screen offers incredibly high capture rates and removes a wider variety of solids, particularly small debris, better than traditional bar screens.
Decanter Centrifuges are used in separation of the solid-liquid or solid-liquid-liquid suspensions. The machine consists of a solid cylindrical bowl rotating at high speed, a scroll rotating in the same axis with a slightly different speed, gear box adjusting the speed difference and the body which carries all the rotating elements.
Decanter Centrifuges are used in many industrial applications such as:
- Oil/Solid Separation (Oil Well Drilling, Refining, De-watering)
- Industrial and Biological Wastewater Treatment
- Food Processing (Olive Oil, Wine, Fruit Juice)
- Fish Processing (Fish Meal, Fish Oil)
- Chemical Slurry
Sludge thickeners are widely used in many wastewater and water treatment plants. Sludge thickeners are also used to increase the sludge concentration for biogas reactors, thus enabling the use of smaller biogas reactors or just as filters to remove coarse material such as fibres in the textile industry. They are generally placed before filter presses, belt press and centrifuges to achieve higher sludge concentration before final dewatering
Greendex proposes SCRUDRAIN® dynamic thickeners with Archimedean screw as the modern and economical solution for sludge thickening. The concentration of D.S. in the outlet from the sludge thickener can be achieved by changing the speed of the Archimedean screw (e.g. sludge with 0.5- 3.0% D.S. can be thickened to 5.0-15.0% D.S.).
Standard SCRUDRAIN® sludge treatment equipment is made of AISI 304 stainless steel.
Scrudrain provides modern and economical solution for sludge thickening
It is considered the new generation of belt filter presses. The Monobelt Press is composed of two units, the pre-thickener and the sludge press.
The pre-thickener performs the initial solid/liquid separation stage, taking sludge solids concentration from 0.5-3% up to 5-15 %. The dewatering in the press occurs firstly in the low pressure zone, then in the wedge zone and finally in the high pressure zone where the filter cake is compressed between the perforated cylinder cloth and the main cloth. The discharged sludge cake can reach dry solid contents variable from of 18 to30% depending on the sewage sludge.
Greendex has the experience and team to assist you in the design, supply and installation of a complete Monobelt dewatering system. The benefits of Monobelt is:
- Integral with thickener and able to take in low solids content sludge
- Very long life endless belt which reduce in maintenance cost
- Small footprint
- Negligible maintenance
