Trouble In Paradise, And A Plan To Alleviate It
12/4/2018
While San Diego has a reputation for beautiful weather in a sunny seaside setting, its growing population in the southernmost area of rain-starved California is a recipe for trouble in paradise. That challenge has spurred the creation of Pure Water San Diego — a multi-phase, multi-year program with the goal of using recycled water for up to one-third of San Diego’s water supply by the year 2035.

Expansion And Upgrade Of WWTP Ozone Disinfection System Reduces Energy Cost By 69%
9/10/2018
The financial cost to maintain their ozone equipment, and increasing scarcity of replacement parts for their ozone generator, motivated a utility in Springfield, MO, to upgrade their ozone system. Read the full case study to learn how the plant assessed the energy cost of a sidestream ozone injection system compared to that of a turbine mixing design and showed that the Mazzei retrofit design reduced the energy cost of ozone contacting by an average of 69.2% under all plant flow conditions.

Improving The Quality Of Tertiary Effluent For Indirect Potable Reuse With Geographic Constraints
9/5/2018
The Mazzei Sidestream Venturi Injection – Pipeline Flash Reactor System provides a feasible alternative for dissolution of ozone at the Clark County Water Reclamation District (CCWRD) in Las Vegas, because it allowed for flexibility in basin design to meet geographic site constraints.

Maximum Ozone Transfer Efficiency Across Broad Range Of Water Flow
8/25/2018
The design team for the intermediate ozone system at Buckingham Water Treatment Plant, Quebec, had limited space available for ozone contacting for the plant’s 1.3 – 7.4 MGD flow, so a standard fine bubble diffusion basin for ozone disinfection was not an option.

Santa Barbara, CuraƧao Desalination Plant: Six Years Of Operation Of LG Chem Thin Film Nanocomposite (TFN) SWRO Membrane
5/14/2018
The Santa Barbara desalination plant located in the south-eastern part of Curaçao provides drinking water to about half of the population of this Caribbean island. With an average precipitation of approximately 500 mm, rainwater is the only natural source of freshwater in the island. Government efforts to address the water shortage problem date back to the 20s of the last century. Initially based on evaporation, the seawater desalination evolved into the reverse osmosis technology in the 90s. After several years of experimenting with RO, Aqualectra, the municipal supplier of potable water and electricity for Curaçao, took the decision to move forward with this technology and in 2003 started a project to build a SWRO desalination plant.

Savings Helps MABRs Gain Traction In Municipalities
5/9/2018
An MABR is essentially a biological wastewater treatment process that utilizes seemingly passive aeration through oxygen-permeable membranes. Oxygen transfer through the MABR membranes is diffusion based: driven by concentration differences such that oxygen passes from air at atmospheric pressure into water at a higher hydrostatic pressure. This oxygen transfer mechanism, wherein air is supplied to the process at very low pressure, is the reason MABRs have significantly lower energy consumption compared to other wastewater treatment processes, such as conventional activated sludge (CAS), that utilize diffusers. This energy savings is one of the key reasons MABRs are gaining traction in the municipal wastewater industry.

Desalinating Brackish Groundwater Eases Water Shortage
4/23/2018
The city of Limassol in Cyprus was experiencing an increasingly severe water shortage, with the growing population and expanding tourist industry placing extra pressure on existing supply. An aquifer in a residential neighborhood was seen as a potential water source, but had high levels of salts and nitrates. The Cyprus Water Development Department (WDD) awarded Fluence a Build-Own-Transfer (BOT) contract to implement a cost-effective solution.
