Rochester Waste Management to address wastewater treatment issues with RO system

The Turnkey Landfill of Rochester under the city's Waste Management will be using a reverse osmosis (RO) system to address the wastewater treatment plant problems, including the low transmissivity levels in the water as well as the significant amount of nitrogen passing through the city's plant. The upgrades are expected to be completed summer of 2013.

A reverse osmosis (RO) system will be implemented for the treatment of leachate — the precipitation and melted snow that filters through the landfill waste and collects on the bottom. After the leachate is pretreated at Waste Management, it travels to the city's wastewater treatment plant, where it's treated and then discharged into the Cocheco River. AQUA SOLUTIONS offer various options in RO pretreatment to meet both laboratory and industrial requirements similar to this.

Tips on Buying a Lab Water Purification System

Buying tips that can help you get the best system for your money! 1.Silence is golden - but make sure the system runs 24/7. Noise does not purify water! The Type I Systems you buy should have a pump that continuously and silently recirculates water 24 hours a day, 7 days a week. Don’t be fooled by intermittent recirculation. It could be a ploy to cover up noisy pumps that were never intended to operate continuously, or pumps that heat up the water.

Why Choose a RO+DI system

Published in Water Filtration

Wednesday, 20 April 2011

Why Choose a RO+DI system

The RO+DI system can produce better quality water, at lower cost, than systems without built-in RO pretreatment. This laboratory water purification system is ideally suited for applications where the existing central RO, DI or distillation pretreatment system is either unreliable, overloaded (with regard to capacity), or nonexistent in a particular location.It is also suitable for applications where either space or funding limitations preclude purchasing separate RO and Type I DI systems.

The RO portion of the system features fully automatic operation. It includes an activated carbon prefilter, product and reject flow meters, one or two TFC (thin film composite) high-capacity RO cartridges, and an external 30, 42, 130, or 200 Liter pressurized tank for storing the RO purified water for later use by the DI system. The Type I DI portion of the system features a high-purity TOC reduction and DI polishing module, continuous recirculation, a digital resistivity monitor that meets USP 29 specifications, a remote dispenser, and a 0.1 micron (absolute) final filter capsule.

The pH of Ultra-Pure Water

It is difficult to measure the pH of type I ultra-pure water. It rapidly picks up contaminants that affect its pH and it has a low conductance, which causes instability in most pH meters unless they are specifically designed to work in ultra-pure water.

Which Type of Reagent Grade Water do I Need?

While many analytical procedures and instruments specify the type of reagent grade water that is needed (i.e., Type I, Type II, Type III or Type IV), just as many do not. As a “rule of thumb”, Type I Ultrapure water contains dissolved solids at the level of “a few parts per billion”, while Type II and Type III water contains dissolved solids at the level of about “1/ 8 to 1/2 part per million”, and Type IV water contains about 2.5 parts per million of dissolved solids.

Choosing the right water system for a lab glassware washer

You are ready to buy a new glass washer for your lab, but you are unsure what water feed system to use? You probably already know what grade water you want to feed your glass washer. In most cases, except for special circumstances for very sensitive applications an ASTM Type II reagent grade water source will be sufficient for your lab glassware washer. ASTM Type II is defined as water that has greater than 1 MΩ/cm2 resistivity.

Ultrafiltration (UF) is similar to reverse osmosis, in that pressure is used to force water molecules through a porous membrane. However, the pores of a UF membrane are about 10 times larger in diameter than the pores of an RO membrane.

Deionization Filtration

Published in Water Filtration

Wednesday, 20 April 2011

Deionization Filtration

Deionization (DI), a.k.a. ion exchange or demineralization, is a process whereby tap water is passed through charged cationic and anionic resin beds containing sites with available hydrogen (H+) and hydroxyl (OH- ) ions. As the ionized contaminants, such as Na+, Ca++, Mg++, Cl-, SO4--, and HCO3-, pass by the ionized sites, the cationic resin exchanges its H+ ion for the Na+ ion, and anionic resin exchanges its OH- ion for the Cl- ion, etc.

Reverse Osmosis Filtration

Published in Water Filtration

Wednesday, 20 April 2011

Reverse Osmosis Filtration

Reverse Osmosis (RO) is aptly named. It actually reverses the natural osmotic process by using pressure to force pure water through a porous membrane. The membrane's pores are sized such that they allow pure water to pass through, while rejecting the contaminants in the water at up to 99% efficiency. In actual situations, the rates of rejection can vary from about 85% to 99% for various contaminants, based on the molecular weight or size of the contaminant and the operating conditions, which include pressure and temperature.

The Basics of Lab Water Purification

Ultra-Pure Water, containing nothing but hydrogen and oxygen, has a specific resistance of 18.2 megohm-cm at 25 °C. Since conductance or conductivity is the reciprocal of resistance or resistivity, a cubic centimeter of pure water has a specific conductance of about 0.055 micromhos (i.e. microseimens) per cm at 25 °C. The conductance arises from the partial dissociation of pure water into hydrogen (H+) and hydroxyl (OH-) ions. Since conductivity is an increasing function of increasing water temperature, the temperature at which conductivity is measured MUST be taken into account. Most conductivity measuring devices simultaneously measure the water temperature, and compensate the conductivity reading as if it were taken at 25 °C.

When do you require Ultra-Low TOC Type I Ultra-pure water?

When do you require Ultra-Low TOC Type I Ultra-pure water?

Pure water is a commodity in many industries in particular in analytical and biologic laboratories. Laboratory grade water is defined by its resistivity, which is determined by the amount of ionic contaminations and by its Total Organic Carbon content (TOC). Resistivity of the water determines the water quality based on American Society for Testing and Material (ASTM) definitions. Many routine laboratory applications use ASTM Type II water that has a resistivity of >1MΩ/cm2 which corresponds to less than 500ppb total ionic contamination. More specialized applications in analytical chemistry and molecular and cell biology require water of ASTM Type I with a resistivity of >18 MΩ/cm2 which corresponds to about 1ppb total ionic contaminations in the water.
