Spiral Separation

Our pre filtration system is the ideal solution for pre-treatment of TSS/BOD in the food and beverage industry wastewater. Fine solids can very efficiently be removed prior to treatment by our Enhanced DAF treatment system. Our next generation automatic, self cleaning filters can overcome the issue present in many food processing plants. Food and beverage plants typically have very high levels of TSS and FOG. Pre-treating these high levels is possible but has historically been limited by requirements for large space and high cost. We have solved both issues with this system.

Description

Our automated pre filter system consists of a metal filter screen and a spiral shaped scraper which continuously cleans the screen without the need for backwash or crossflow. This is achieved by the system automatically cleaning itself over 500 times every minute.  Automatic self-cleaning water filter designed for ultra-high and variable TSS of up to 25,000 ppm.

Process Explained

The system operates on the core principles of a mechanical filter. During normal operation solids are collected at the bottom of the housing, away from the filter, while filtered water flows continuously through the outlet. An automatic purge valve opens and ejects the concentrated solids with a minimal amount of water loss. TSS and BOD are reduced without the introduction of any chemicals or additional pollutants. Collected solids are concentrated to a sludge that can be further dewatered as desired.

Spiral Separation Filtration Family

Spiral Shaped Brush/Filter Screens

The spiral shaped brush is designed to rotate continuously, so there is always less than 1 psi head loss across the filter screen. Flow through the filter unit is limited by both solids loading and hydraulic loading on the screen. Flow rates listed below assume a viscosity of 1.0 cP and TSS up to 1000 mg/l. A control system can be purchased which will monitor the solids build up in the housing and open the purge valve when necessary. Operating pressure in the 5 to 20 psi range is optimal, though the unit is capable of operating at 150 psi.
