A Ground-Breaking Innovation In Wastewater Treatment
The fashion industry contributes 20% of industrial water pollution With a high water footprint, massive chemical use and atmospheric, water and greenhouse gas (GHG) emissions, dyehouse operations are the most environmentally damaging component of the apparel supply chain2.Global brands are responding by requiring manufacturers to treat wastewater and reduce effluent. Paradoxically, conventional water treatment systems generate toxic sludge, trading water pollution for solid, chemical discharge that is landfilled and emits GHG – mostly methane.

Small Wastewater Treatment Works DPW Design Guidelines
This document’s purpose is to direct the design process for designing the best and most Appropriate wastewater process for effluent which is generated by small scale on site operations, Up to 100 m3/day such as police stations, border posts, DOJ etc. Larger plants are also addressed To some extent. In this manual, the best appropriate process for such small waste water treatment Plants has already been identified as the Rotating Biological Contactors (biodiscs) systems and Biological trickling filters (biofiters) for larger quantities. Consultants designing such plants for The DPW need to take cognizance of all the criteria set out herein and must ensure that apart from That the best available practices as regards such processes are incorporated into the design. The Designers of such plants are however still to consider other alternatives if the circumstances so Dictate.

Boron Rejection by Reverse Osmosis Membranes – National Reconnaissance and Mechanism Study
Introduction
The mechanism of boron rejection by reverse osmosis membrane and transport was studied by bench experiments using six commercial reverse osmosis membranes.
A mathematical model was developed to predict boron rejection by reverse osmosis membranes under different operating conditions such as pressure, pH, and temperature.
Boron concentrations in feed and product water from nine pilot or full-scale plants were analyzed in parallel.
Comparison with bench-scale data suggested that the level is much lower than the boron rejection observed in the field data, mainly due to the high target recovery rate.
