Designing the Kinnet Tunnel for a 100-Year Service Life
The Kinnet tunnel. Image courtesy: Arava Drainage and Streams Authority / Glimmer - Industrial Consultation The Kinnet tunnel was designed to collect flood water from the entire Arava region and the city of Eilat, Israel. It is being constructed in a highly aggressive environment with sulfate-rich ground and extremely hot weather conditions. Moreover, the regions’ flood water is considered soft water, which contains very few minerals and is very aggressive toward concrete. The aggress...
New ASCE Standard 69 Addresses Current Practices for Managed Aquifer Recharge
Reston, Va. – Ongoing demand for water supplies and the need for water storage have led Managed Aquifer Recharge (MAR) to becoming an increasingly important component for both storage and supply in regional water planning and management. ASCE’s new standard, Standard Guidelines for Managed Aquifer Recharge, ASCE/EWRI 69-19, provides a thorough and up-to-date description of MAR projects. This standard provides details on planning, design, construction, operation, monitoring, and closure of MAR...
First Commercial Order of a Next-Generation Ultra High-Pressure Reverse Osmosis (UHP RO) Industrial System
RICHMOND, British Columbia - Saltworks Technologies is thrilled to announce the first full-scale order for an industrial Ultra High-Pressure Reverse Osmosis (UHP RO) system with Nitto high performing HYDRANAUTICS™ PRO-XP1 spiral wound membranes rated to 1,800 psi (124 bar). Ultra high-pressure RO builds on the pedigree of seawater reverse osmosis systems, but operates at 50% higher pressure—beneficially halving the volume of brine generated. This means less waste and more clean water. Saltw...

Microvi MNE Outperforms Established Tertiary Ammonia Removal Process at Thames Water Wastewater Treatment Plant
Thames Water Utilities Ltd. and Microvi Biotechnologies completed a collaborative 9-month trial demonstrating Microvi's novel wastewater treatment, Microvi MNE™ (MNE). The fully automated MNE demonstration plant was configured as a tertiary nitrification system for ammonia removal. Operating between 5-22 degrees Celsius, MNE consistently removed ammonia from wastewater during continuous operation outperforming the ammonia removal rates of the existing nitrifying sand filters. MNE showed resi...
Rice Engineers: Make Wastewater Drinkable Again
A schematic representation of the hybrid water supply system developed by engineers at Rice University. The researchers suggest that delivering water to city dwellers can become far more efficient, and that it should involve a healthy level of recycled wastewater.
