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…
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…
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…
Water-supply issues are emerging as a national concern with certain sectors coming under increasing scrutiny. This is certainly the case with the ethanol industry. State discharge regulations dictate that plant designs incorporate technological solutions to minimize water use. These designs…
A research team from the University of South Australia (Adelaide; www.unisa.edu.au) and the East China Normal University (Shanghai; www.ecnu.edu.cn) has developed a capacitive deionization technology (CDI) that uses graphene-like nanoflakes as electrodes, instead of conventionally used activated carbon (AC) materials.…
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…
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…
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…
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…
Dow Water and Process Solutions (DW&PS; Minneapolis, Minn.; www.dowwaterandprocess.com), a business unit of The Dow Chemical Co., unveiled a simplified electrodeionization (EDI) product at the recent Singapore International Water Week event. The new version of the product reduces operating costs…
