nuwell 100

Nu-Well 100

This product is a pelletized acid is formulated for pouring directly into the well. While it may be dissolved and pumped into the well as a liquid, the pellet form rapidly falls through the water column, providing concentrated acid cleaning power at the bottom of the well. The sinking pellets are ideal for wells with short to moderate lengths of screen at the bottom. Agitation of the acid into the blocked area will greatly enhance cleaning. The acid solution should remain in contact for a period of 12 to 24 hours, depending on the nature of the blockage. The table provides recommended dosages for general well cleaning. The amount of acid consumed will depend on the degree of mineral scaling in the well.

Application

Nu-Well 110 Granular Acid is used in well cleaning operations as a granular product introduced at the well head or dissolved and pumped into the well as a liquid. The granular form can settle throughout the water column providing a simple application, however, for improved cleaning, it is recommended to pull the pump and treat the well as follows:

1. Nu-Well 110 Granular Acid should be mixed into a tank containing a volume of water and acid equal to 40% of the total treatment volume. The attached table provides the recommended dosage for general well cleaning. When possible, obtain information on construction and performance history and submit samples for laboratory analysis before application to determine if dosage modifications are warranted.
2. This mixture should be placed evenly across the well screens. Placement methods should assure contact with affected regions at the desired concentration. Agitation of the acid into the plugged area will greatly enhance the effectiveness of the cleaning.
3. The acid solution should remain in contact for a period of 12 to 48 hours, depending on the nature of the plugging. The product has limited use where heavy deposits of gypsum are suspected (add Nu-Well 310 Bio-acid Dispersant in this situation).
4. Monitor pH often during treatment and keep below 3.0 for effective cleaning. If pH rises above 3.0 add an additional acid solution of approximately 20% of the original dose. The amount of acid consumed will depend on the degree of mineral scaling.
5. Discharge the acid solution from the well, neutralize on the surface and dispose of in accordance with the appropriate regulations.

Nu-Well 310

Nu-Well 310 bio-acid dispersant is a unique polymeric-acid chemistry that is the most effective product available for breaking down biofilm and dispersing mineral salts. It provides a considerable boost to any acid-cleaning operation, is readily biodegradable and may be used to treat potable water systems and related equipment. Maintains the acid reaction, holding minerals in suspension at pH levels of 3.0 and higher. Controls sludging by preventing re-precipitation or adhesion, for thorough removal of biological material during flushing.

Description
• Dislodges biofilm masses associated with iron oxidizing, sulfate-reducing and more prevalent slime forming bacteria, which are not removed by mineral acids alone
• Sequesters iron and inhibits corrosion on metal surfaces. Iron sequestering allows the chemical solution to remove heavy accumulation of iron compounds, often the cause of fouling water systems
• Protects all forms of metal in the system and will not attack plastic, neoprene or other synthetic materials, eliminating the need for acid inhibitors
• Provides passivation of metals when used with phosphoric acid
• NSF approved for cleaning potable water wells, pipelines and filter systems
• Nu-Well 310 bio-acid dispersant is an acid-based liquid. Avoid contact with strong alkaline materials or oxidizers. Use personal protective devices (PPD) and clothing, especially where the possibility of inhalation exists. Most acids and alkaline materials will not affect Nu-Well 310 bio-acid dispersant at concentrations below 25 percent
• Non-bioaccumulating
• 1 gallon containers in stock and 5, 30, and 55 gallon containers available upon request

Application

Nu-Well 310 bio-acid dispersant is designed for mixing with acid solutions to improve the acid cleaning reaction. Standard dosage is 3 percent (1 to 2 percent for maintenance). Dosage of Nu-Well 310 bio-acid dispersant can range from 0.5 to 5 percent (by weight) of treatment volume.
Optimal concentration depends on the type and severity of the deposit. It is recommended that well construction and performance history be submitted, along with water samples for lab analysis, to properly determine dosage on large municipal and industrial wells.

1. Surface prepare a solution of water, acid and Nu-Well 310 bio-acid dispersant equal to approximately 40 percent of the total static volume into a vessel of appropriate size. First add water, then acid, then Nu-Well 310 bio-acid dispersant. (Note: NEVER add water to acid! DO NOT mix Nu-Well 310 bio-acid dispersant directly to commercial concentrations of liquid acid, as polymer destruction may occur.)
2. Place the surface-solution evenly across the intake zone, ensuring contact with affected areas at the recommended concentration. Agitate the cleaning solution to enhance the effectiveness of cleaning
3. The solution should remain in contact for 18 to 48 hours, depending on the nature of the deposit. Monitor the pH and keep it below 3.0 during treatment. If additional acid is needed (to lower pH), add an amount equal to approximately 20 percent of the initial amount of acid applied
4. Discharge the acid solution from the well, neutralize at the surface and dispose in accordance with local regulations

steriline

Sterilene

Jet-Lube®STERILENE is a sodium based, granular chlorine that does not require a control of pH using vinegar or acid to make it effective. It is far more effective than any other standard chlorine (liquid sodium hypochlorite or calcium hypochlorite). This means a lower cost, no premixing, and far less failures. It is non-oxidative which means, it will not cause corrosion and there are no corrosive fumes during usage and it will oxidize soluble minerals in water, causing discoloration. This product will not cause obtrusive, chlorine odors when used at the proper dosage levels.

JET-LUBE® STERILENE is used to mitigate and control bacteria and other organisms which can create a slime that result in plugging and a reduction of the yield in a well. STERILENE is used as a source of free available chlorine (FAC), in the form of hypochlorous acid, for the disinfection of water. It is used as a means of disinfecting drinking-water, primarily in emergencies, when it provides an easy-to-use source of free chlorine, and more recently, as the form of chlorine for household potable water treatment; recognized acceptable by the World Health Organization.

Benefits
• 55% available chlorine
• Granular but easy to mix, even in cold water
• No premixing to control pH
• No corrosive fumes
• No shelf life limitations
• Easy to use
• Long lasting
• NSF 60 certified
• Available stock in ½ lb. (227 g) jar and 1 gallon (3.9 kg) container and 5 gallon (22.68 kg) available upon request

Application
Dosage recommendations are 100 ppm.

Less than 200’ of water in the well:
Dosage chart on the 8.5 and 50 lb containers. This automatically calculates 2 volumes of the well per foot of water in the well. Multiply the footage of water in the well by this well volume. Have a mix tank at the well head with this amount of water. Start a pump, recirculate in the tank and slowly pour JET-Lube Sterilene into the intake of the pump for mixing. Pump or pour into the well.

More than 200’ of water in the well:
Follow the dosage and multiply by the total footage of water. Mix in a surface tank. Set a tremie line and displace the chlorine solution in 40’ increments from the bottom of the well upwards to the static level. For either condition, surge the well or recirculate chlorine with the pump. Pump into the system until a chlorine residual. Let set 4-5 hours or overnight. Pump to waste.
