VoxSton – A New Water Clarification System

Abstract

A new water clarification system for industrial and communal wastewater is presented here. The system consists of two centrifugal separators, a screw separator and two vortex flow flotation units. It can separate the solids like fibers out of the sludge and press them to dry matter content of up to 30 percent and clean the sludge water for recycling and discharge to nature. The clarification system can, in most cases, treat process and communal sludge continuously or daily basis directly from outlets of the wastewater to be treated to finish without equalization and precipitation. The objective is to recycle the process and wastewater, and to collect different ingredients for reuse as much as possible, and to prevent microbe growth. The new system saves in energy and space as well as in operational costs by roughly 50 percent compared to present advanced systems. The capital costs are estimated to be lower too. The new treatment or part of it has been applied for purification of various water matrices from city and industrial wastewaters to natural lake waters.
