2. Why choose to work with LT Technologies? Isnt bigger better?
This is a question we get asked frequently. Prospects, many times think they will get better pricing and service after the sale from mega companies. We could not disagree more! And we can prove it... We have purposely kept this firm small and super responsive to our customers need as a direct result of our experiences working with and in some cases, for, much larger companies. When you call us we answer the phone. We work with you to design based on budgets and not products. We are innovative and realistic...A rare combination in our industry. All we ask is for a chance to show you the difference and the savings.

3. Do you offer Preventative maintenance & Service Contracts?
Preventative maintenance makes your investment last. We know from experience that the harshest environment in the world can be found in a productive manufacturing environment, out in the field in an unmanned ground water environment, or in a bottling facility where millions of gallons of product water or waste water is flowing 24/7..We have designed our services to be affordable fast and filled with value. For over 20 years our clients have trusted us with ensuring the longevity of the systems we service and we have the expertise and technical capabilities to keep you running. We offer a full spectrum of services such as the re-bedding of carbon and resin columns, to the replacement of membranes, pumps and controls. Call us to learn more about the services we offer in your geographic area.

4. How Reverse Osmosis works
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration. Osmosis is a special case of diffusion in which the molecules are water and the concentration gradient occurs across a semi-permeable membrane. The semi-permeable membrane allows the passage of water, but not ions (e.g., Na+, Ca2+, Cl-) or larger molecules (e.g., glucose, urea, bacteria). Diffusion and osmosis are thermodynamically favorable and will continue until equilibrium is reached. Osmosis can be slowed, stopped, or even reversed if sufficient pressure is applied to the membrane from the 'concentrated' side of the membrane. Reverse osmosis occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration. To illustrate, imagine a semi-permeable membrane with fresh water on one side and a concentrated aqueous solution on the other side. If normal osmosis takes place, the fresh water will cross the membrane to dilute the concentrated solution. In reverse osmosis, pressure is exerted on the side with the concentrated solution to force the water molecules across the membrane to the fresh water side.

Semi-permeable refers to a membrane that selectively allows certain species to pass through it while retaining others. In actuality, many species will pass through the membrane, but at significantly different rates. In RO, the solvent (water) passes through the membrane at a much faster rate than the dissolved solids (salts). The net effect is that a solute-solvent separation occurs, with pure water being the product. (In some cases, dewatering is desired to concentrate the salts).

5. How does Ion Exchange work
Ion exchange resins are polymers that are capable of exchanging particular ions within the polymer with ions in a solution that is passed through them. The synthetic resins are used primarily for purifying water, but also for various other applications including separating out some elements. A standard dual bed ion exchange unit consists of a strong acid cation resin that exchanges hydrogen for positively charged cations present. The second step is a week or strong basic anion resin that exchanges hydroxide for negatively charged anions present in the water stream. The hydrogen (H+) from the cation exchanger and hydroxide (OH-) from the anion exchanger create the HOH or deionized water to be reused in the process.

There are certain processes that generate an abundance of either a cation or an anion. If this occurs, a more selective weak acid cation can be used to exchange the multi-divalent heavy metals that are in abundance. This "pre-treating" of the heavy metals will assist in the exchanging of the mono-valent cations. A weak basic anion before the strong basic anion can be implemented to assist in pre-treating for hexavalent chrome.

The cation ion exchange resin are regenerated with an acid to exchange the hydrogen back onto the cation resin beads. The anion is regenerated with sodium hydroxide to exchange the hydroxide back onto the anion resin beads.

6. How does Microfiltration work
Cross-flow microfiltration (CFMF), is a process for separation of larger size solutes from aqueous solutions by means of a semi-permeable membrane passed over the filtration medium. Clear liquid permeates the filtration medium and is recovered as the permeate, while the solids accumulate at the filtration barrier to form a fouling layer, or cake. The cake, constituting an increase in hydraulic resistance, decreases the permeate flux. However, the tangential suspension flow tends to limit the growth of the cake. Thus, after an initial rapid increase in cake thickness, cake growth ceases, and the cake thickness becomes limited to some steady-state value. Correspondingly, after an initial rapid decrease, the permeate flux levels off and either attains a steady-state, or exhibits a slow, long-term decline with time. Microfiltration is suited to separate larger sizes, such as suspended solids, particulates, and microorganisms. This is accomplished because microfiltration membranes are thought to act like a physical seive. The membranes are highly porous and have discernible pores even when the surface skins are asymetric. Therefore, the separation is based mainly on size. Membrane material is usually made up of ceramics, teflon, polypropylene, or other plastics.
