Headworks Odor and Corrosion Control Using Hydrogen Peroxide

by USP Technologies     based in Atlanta, GEORGIA (US) (USA)

Hydrogen Peroxide typically controls odors and corrosion at treatment plant headworks by direct oxidation of hydrogen sulfide (H2S) within the wastewater. In the direct oxidation mode, H2O2 is applied to the wastewater 5-30 minutes prior to the point where the odors are being released, generally as the wastewater line enters the plant boundary. The efficiency of hydrogen peroxide treatment depends upon the available reaction time, the level of iron in the wastewater (reaction catalyst), wastewater pH and temperature, and the initial and target levels of H2S odor. Under optimal conditions, effective dose ratios are 1.2 - 1.5 parts H2O2 per part dissolved sulfide, and can be reliably estimated through beaker tests. H2O2 + H2S → S0 + 2H2O Frequently, control of odors through the primary clarifiers is wanted. In such case, the mechanism of control is both direct oxidation of H2S (as it rises from the solids blanket), and prevention of odor generation (by supplying dissolved oxygen). Control is typically achieved with a booster dose of 1-2 mg/L H2O2 added to the clarifier influent. Higher doses or alternate modes of addition may be required in cases where: 1) hydraulic retention times are > 2-3 hours; 2) solids blanket depths are > 1-2 feet; 3) soluble BOD levels are > 200-300 mg/L; or 4) waste activated sludge is co-settled with the primary solids. 2H2O2 → O2 + 2H2O

Groundwater Monitoring for Water Management

by HERON Instruments Inc.     based in Dundas, ONTARIO (CANADA)

Fresh water is one of the planets most critical resources essential to all land based life It is also one of the planets most rapidly diminishing resources. Conservation and protection of existing supplies and the rehabilitation of degraded sources are one of the most urgent problems facing humanity today.

APHA Color #3020

by Guided Wave Inc,     based in Rancho Cordova, CALIFORNIA (USA)

Measurement of APHA color either on-line or in a laboratory setting using a photometer. Background: APHA is sometimes referred to as the Platinum Cobalt (Pt/Co) or Hazen scale. Also referred to as a “yellowness index”, the APHA color scale is a common method of comparison of the intensity of yellow-tinted samples to assess the quality of liquids that are clear to yellowish in color. Originally developed to determine the purity of municipal water supplies, it is now used as a metric for purity in the water, chemical, oil, plastics, and pharmaceutical industries. APHA color quantifies the appearance of trace amounts of yellowness, which is a visual indicator of product degradation due to exposure to light or heat; the presence of impurities and negative effects of processing. As such APHA color is often used as a product release specification. APHA is a single number yellowness index. The units are based on a dilution of a 500ppm solution of PtCo.

Water Treatment Solutions for Nitrate Removal

by Adedge Water Technologies, LLC     based in Buford, GEORGIA (US) (USA)

Most nitrogenous materials in natural waters tend to be converted to nitrate, so all sources of combined nitrogen, particularly organic nitrogen and ammonia, should be considered as potential nitrate sources. Primary sources of organic nitrates include human sewage and livestock manure, especially from feedlots. The primary inorganic nitrates which may contaminate drinking water are potassium nitrate and ammonium nitrate both of which are widely used as fertilizers. According to the Toxics Release Inventory, releases to water and land totaled over 112 million pounds from 1991 through 1993.

Pure drinking water solutions for day care & preschools

by Pure & Secure, LLC.     based in Lincoln, NEBRASKA (USA)

CHILDREN ARE ESPECIALLY SENSITIVE TO TOXINS IN WATER. Children are much more sensitive to chemicals in the water supply than adults. A child’s brain continues to grow after birth, and this development process is very sensitive to chemical interference. Research now suggests that a single small dose of a chemical on a critical day of development can cause permanent learning disorders*. Now you can show parents that your preschool is the market leader in protecting their children from toxins that could be present in your tap water. Our premium water distillers allow you to provide your children with fresh, distilled water, the safest drinking and cooking water available.

Monitoring of Algae in Drinking Water

by Chelsea Technologies Group     based in West Molesey, UNITED KINGDOM

The UniLux in-situ fluorometer can be configured to detect a number of key parameters that are of importance to the Water Supply Industry. Primarily, the detection of Chlorophyll a in stored water systems, such as reservoirs, assists in the planning and informs decisions on water abstraction in relation to natural algae blooms that regularly occur throughout the year. As well as Chlorophyll a, these in-situ fluorometers can detect cyanobacterias, such as Phycocyanin and Phycoerythrin, which are often associated with algae groups of a toxic nature. Knowledge of concentrations of algae within the water can assist in determining the loading into water processing plants.

These in-situ fluorometers are available as single parameter sensors (UniLux), or 3 channel sensors (TriLux).The CTG FastFlow fast repetition rate fluorometer provides information on the physiological state of algae it monitors. As well as providing detailed information on the growth rate of the algae (which can indicate the occurrence of a future algae bloom), it can immediately inform and alarm on toxins that have accidentally or deliberately been introduced into the water systems, as with the FastGuard system. The FastFlow differs from the FastGuard system in that it logs and displays detailed information on the state of the algae monitored for operational requirements.

Concerned about PAHs in Parking Lot Sealcoats?

by Sitelab Corporation     based in West Newbury, MASSACHUSETTS (USA)

There is growing concern - and regulations in the works - over the use of sealcoating products due to their high PAH content.  In the United States and elsewhere, most sealcoats are made from coal tar which can be toxic to aquatic life and threaten public water supplies from rain and runoff. Sitelab can be used to quickly check the concentrations of polycyclic aromatic hydrocarbons and determine if it's made from coal tar or alternative petroleum based black top sealants.  Got samples?  We'll test them for free!  Contact Sitelab Corporation for details.

Turbidity Monitoring

by Chelsea Technologies Group     based in West Molesey, UNITED KINGDOM

The monitoring of Turbidity is key requirement of the water industry in both water supply and water recovery systems. Within the water supply process, monitoring of turbidity allows operators to assess the efficiency of filters for particulate removal through the process. Similarly, with water recovery (Waste Water Treatment Works), the measurement of turbidity is a key parameter to track the removal of particulate through the process. CTG can provide turbidity measurements with the UniLux sensor, or provides turbidity as one of the parameters available within the 3 channel TriLux. For applications requiring turbidity measurements compliant to ISO07027:1999, CTG can offer the TurbiLux Nephelometer.
