The focus of this presentation is the use of oxidant(s) to enhance ultraviolet (UV) disinfection based on an ongoing project at Tampa’s Howard F. Curren Advanced Wastewater Treatment Plant (HFCAWTP). This approach is unique because it would be the first of its kind in Florida. Systemic bench-scale testing and on-site water quality measurements are used to evaluate the oxidant-enhanced UV ...
The season of investing water park equipments has arrived, many investors have started to move. If you really want to operate a water park equipment, the choice of water park equipments are on the one hand, on the other hand, an important point is the choice of the park site, the site is directly related to the follow-up of the water park business, is the operator should carefully investigate and ...
Bacteria have been detected in many water supplies on dairy farms, and the water used to wash milking equipment should be free of bacteria. This study evaluated two ultraviolet (UV) technologies, with and without automatic sleeve cleaning device, as on-farm water disinfection system. No fouling was observed during 6 months of continuous operation of the self-cleaning UV system. The dose provided ...

Issue Although there have been limited documented illnesses due to cross-connections between reclaimed and potable water, our industry must manage the perception of public health risks. The proliferation of reuse utilities is limited by public acceptance of reuse water. Safety measures protecting the public from potential health hazards are critical to the public acceptance of reuse water. The ...
STS and Yorkshire Water have been working on monitoring siloxanes at two of their waste water treatment sites. Yorkshire Water wanted to gain a better understanding of the level of siloxane contamination in the biogas derived from Sewage AD and how the contaminant may vary over time. STS installed their Pre-Packaged monitoring kiosk for 2, 6 week trials with data being collected through a web ...
In September 2006, Diamond Lake was treated by the Oregon Department of Fish and Wildlife with a mixture of powdered and liquid rotenone in the successful eradication of invasive tui chub Gila bicolor. During treatment, the lake was in the middle of a phytoplankton (including cyanobacteria Anabaena sp.) bloom, resulting in an elevated pH of 9.7. Dissipation of rotenone and its major metabolite ...
Spider boom is also called manual placing boom, it is a type that differs from the hydraulic placing boom. Spider boom pump needs operator to pull the rope to control the arms, adjust working radius or area. Make sure the concrete is delivered to the certain position and thus continuous casting. Small size, lightweight, easy to lift and transfer. The structure is stable and reliable, adopting ...

The objective of this paper is to assess the potential for energy savings in water and sewerage services by means of on-site integrated water and sewage management strategies in low-income households in Florianópolis, Brazil. The on-site water efficiency measures include reclamation of gray water and rainwater use. The water and energy saving potential of both strategies were studied, and ...

Since it was first settled in 1841, the San Gabriel Valley has hosted a variety of industries, ranging from walnut packing to rocket fuel manufacturing. Along with other contaminants, industrial development has left a significant portion of the Valley’s groundwater contaminated with: - N-nitrosodimethylamine (NDMA) and - 1,4-Dioxane. NDMA entered the groundwater in the San Gabriel ...
Background CL-Out was successfully used to remediate TCE in ground water at a former industrial site near Newark. The affected ground water was perched on siltstone bedrock in a mix of fill and alluvial sand deposits. The cleanup goal was to reduce the contaminant mass sufficiently to meet site-specific goals to prevent vapor intrusion and offsite migration ...
Your desalination unit is one of the water treatment systems on your offshore rig that helps ensure that you have the water you need for daily functions at sea. As such, it’s critically important to the safety of your crew. Offshore platforms are often located in the most remote, inhospitable places on the planet. Entire crews-often, hundreds of people-work on and call these platforms home. ...
Performing stormwater drainage design is one of the requirements of a site designer. Recent regulations created and enforced by the EPA require new developments to limit the amount of stormwater that flows off of a newly developed site, to be equivalent to or less, than the flow rate prior to development. The site designer must determine how much water is running off the original site, and ...
This document describes how to properly install the Rainstore3 water storage system with geomembrane for stormwater containment and reuse. Containment allows for on site subsurface water storage for many non-potable applications such as irrigation. Contractors: Only licensed contractors should install the Rainstore3 system. The contractor should have a good performance record with similar ...
We live in a world where not everything goes according to plan, especially in the case of a business. How in business? Well, we all want our business to grow, and it takes blood, sweat, and tears to make that possible. Still, after doing all the hard work, there are chances that your success could be wiped out by losing your company’s valuable data due to any number of reasons. It could be a ...
Location: Houghton Lake, MI Cofferdam Size: 8′ high x 150′ long. Water Depth: 6′ Installation Time: 4.5 hours Project Description: Remove bottom sediment to deepen canal for improved boat access. The dredging process can be greatly expedited with the use of water-filled cofferdams from Dam-It Dams. By holding back water on the site, excavators ...
Coliforms are the most widely accepted bacterial indicator of fecal pollution in water. Several commercially available portable kits make it possible to carry out on-site water quality testing, but are usually costly and often require technical expertise to operate. In developing countries like India, presence/absence test kits like the H2S test kits are commonly used for routine ...
ABSTRACTOn-site detention (OSD) of storm runoff decreases catchment peak flows through the routing effect of temporary storage; on-site retention (OSR) achieves the same objective by abstracting part of the urban flood wave and passing the retained water to disposal on site. The investigation explored both strategies applied to a set of hypothetical present/re-developed urban catchments ranging ...
