    Microplastics in Water

    Dan Jackson


    What are Microplastics?

    Microplastics are considered plastic particles 5mm (5000 microns) in size or less.  Plastic particles are in wide use in industries such as cosmetics, ion-exchangers in some water filtration systems, air blasting technology, tires, etc.  Microplastics are divided into two classes:  Primary microplastics are in their original form, and secondary microplastics are smaller pieces derived from breakdown of primary microplastics.  Microplastics have a very long degradation process that contributes to buildup in the environment.

     

    Are there health concerns with Microplastics?

  3. Guide for "Salt-Free" Water Softening

    Salt-free softening guide

    Water hardness is measured by the amount of calcium and magnesium minerals in water. Within the water quality improvement industry, Grains per gallon (gpg) is the most common method for designating the water hardness. Lab reports may express hardness using parts per million (ppm) or milligrams per liter (mg/L). Multiply the grains per gallon by 17.1 to get the equavalent ppm or milligrams per liter.

    The Water Quality Association breaks down water hardness into the following categories:

    • Soft:   < 1 gpg   (<17.1 mg/L)

    • Slightly hard: 1 to 3.5 gpg (17.1 to 60 mg/L)

    • Moderately hard: 3.5 to 7.0

  4. Carbon Basics

      Carbon Basics

    • Granular activated carbon is commonly used for reducing organics and residual disinfectants from water supplies. This im-proves taste and protects water treatment components such as reverse osmosis membranes and ion exchange resins from possible damage due to oxidation or organic fouling. Typical surface area for activated carbon is approximately 1,000 square meters per gram (m2/gm). However, different raw materials produce different types of activated carbon varying in hardness, density, pore and particle sizes, surface areas, extractables, ash and pH. These differences in properties make certain car-bons preferable over others in different applications. The two principal mechanisms by which activated carbon removes con-taminants from water are adsorption and catalytic reduction. Organics are removed by adsorption and residual disinfectants are removed by catalytic reduction.

  6. Nominal Rejection Performance of Standard TFC Reverse Osmosis Membranes

    Nominal rejection performance table below is extracted from Water Quality Association knowledge base for standard thin film composite reverse osmosis membranes operating at operating at a net pressure (feed pressure less back pressure and osmotic pressure) of 60 psi and 77°F water temperature. Performance of ro systems utilizing TFC membranes may be less due to changes in feed pressure, temperature, water chemistry, contaminant level, net pressure on membrane, and individual membrane efficiency. Tank-less RO systems (such as countertop ROs) and ROs with atmospheric tanks produce better overall rejection performance than undersink ROs (or ROs with pressure tanks) due to maximizing of net pressure on membrane.

  7. Understanding the Benefits of a Whole House Water Filtration System

    Homeowners express a variety water quality concerns ranging from aesthetics to contamination fears. It’s unfortunate that many people, out of frustration or ignorance, never find a suitable solution to their water worries. There is no reason to let “bad water” ruin your healthy lifestyle or damage your largest single investment-your home! Take a look at these common water-quality issues homeowners face every day:

    • Tap water that tastes and smells like a swimming pool, due to chlorine disinfectants
    • Discolored well water from tannins
    • Rotten egg odors from hydrogen sulfide
    • Premature water heater failure
    • Red stains in the sink, tub and toilet due to iron
    • Blue-green copper stains in the toilet and shower
    • Crusty hard-water mineral build-up on faucets and shower heads
    • Grit-clogged faucet aerators, dish washers and washing machines
    • Nitrate contamination in well water
    • Bad-tasting

  8. Nitrite in Water

    Source of Nitrite: Nitrite (N2O-) is a nitrogen-containing chemical similar to nitrate. Nitrogen in fertilizers, animal waste from farms and decaying plant materials can introduce nitrite into groundwater. Malfunctioning septic systems can also be a source of nitrite in well water. Nitrite can be found in municipal water but it mostly occurs in well water.

     

    Health Effects of Nitrite: Nitrite reduces the blood’s ability to carry oxygen. This causes a condition called methemoglobinemia. Babies and pregnant women are particularly susceptible to nitrite poisoning. Ingesting nitrite can have a negative impact on the development of the child. Blue Baby Syndrome causes the infant to turn blue and suffer from lack of oxygen.

     

    How to Remove Nitrite: A WECO reverse osmosis filtration system will remove nitrite along with nitrate, taste and odor-causing chemicals like chlorine and

  9. Hydrogen Sulfide in Water

    Hydrogen sulfide

     

    Source of Hydrogen sulfide: Hydrogen sulfide (H2S) is a colorless gas with a “rotten egg” smell. It is sometimes called sewer gas or sulfur water. Certain bacteria decompose organic matter and release hydrogen sulfide gas into groundwater. Wells contaminated with manure or human waste can also have H2S problems. Turning the water heater thermostat too low allows bacteria to grow inside the tank and produce the smelly gas.

     

    Effects of Hydrogen sulfide: Hydrogen sulfide can give water a bitter taste and offensive odor. High hydrogen sulfide levels may also corrode plumbing, washing machines and ruin laundry.

     

    How to Remove Hydrogen sulfide: A WECO reverse osmosis filtration system will remove hydrogen sulfide along with taste and odor-causing chemicals like chlorine and hydrogen sulfide and heavy metals including lead and

  10. Escherichia coli in Water

    E. coli in Water

    Source of E. coli: E.coli (Escherichia coli) is a group of naturally-occurring bacteria. Some strains are harmless while others affect human health. These come from animal waste that contaminates the water supply.  The presence of E. coli in water is used as an indicator of possible contamination with the harmful bacteria strains.

     

    Health Effects of E. coli: Harmful E. coli strains produce toxins that causes symptoms including pneumonia, stomach cramps, bloody diarrhea and vomiting. 


    How to Remove E. coli:  A Polaris Scientific Ultraviolet Disinfection System is recommended to counteract E. coli contamination. The Polaris system will kill the bacteria as water passes through the UV radiation, rendering the water safe to consume. The Polaris UF system can be used on residential and commercial applications.
