Water Treatment

A control device that cuts energy consumption for making WFI

Christ Aqua Pharma & Biotech The new WFI-Flex (WFI = water for injection) power control can help reduce energy costs in water treatment. With the WFI-Flex control for all multi-stage water systems, operation is possible in a range from 10…

This photometer measures a wide range of concentrations

The DCP007 Series of industrial photometers (photo) can measure the concentration of light-absorbing substances over the wavelength of 280 to 2,000 nm. The new units use solid-state LED lamps and laser diode technology, and a dual wavelength, four-channel measurement technique…

When space is limited, consider this ultrafiltration rack

The T-Rack vario ultrafiltration module is said to have a 60% smaller footprint than conventional racks. The unit’s modular design means the rack can be configured to match each user’s specific requirements. Each row can be operated as a separate…

Zero-liquid-discharge desalination system offers brine disposal alternative

A desalination system developed by Watervap LLC (Marble Hill, Ga.; www.h2ovap.com) separates saltwater of any concentration into highly purified water and dry solid minerals with high efficiency. The company’s Zero Liquid Discharge (ZLD) process represents a low-cost alternative to brine…

Focus on Process Water Treatment

BioAir Solutions Clean the air from wastewater treatment plants without carbon Using its proprietary EcoBase synthetic media, this firm has developed a line of odor control products (photo) that remove both organic and inorganic odorous compounds from the airstreams of…

Ask the Experts: Water-hydrocarbon separation

Question: How are hydrocarbons best removed from water? Answer:  First, the type of hydrocarbons present must be identified. Typically, the hydrocarbons in question are in the form of oil or an oil-like substance. In that case, the miscibility of oil…

Desalination: From Sea to Shining Sea

Athough the municipal water demand is considerably greater than that of industry, many of the municipal needs are addressed by relatively basic technologies, while industrial requirements can only be met with advanced treatment options. And, as industrial water demands continue…
