Chapter 1: Techniques
Ecolochem's Deox technology employs a multifaceted approach to dissolved oxygen and gas removal, leveraging several key techniques:
Deaeration: This involves the physical removal of dissolved gases. Ecolochem utilizes both traditional and advanced deaerator designs. Traditional tray-type deaerators utilize steam injection to heat the water, reducing gas solubility and releasing dissolved gases. Advanced spray deaerators improve efficiency by atomizing the water into fine droplets, maximizing surface area for gas release. Vacuum deaerators reduce pressure to facilitate gas removal. The choice of deaerator depends on factors like flow rate, pressure, and desired oxygen level.
Chemical Oxygen Scavenging: This technique employs chemical additives that react with dissolved oxygen, converting it into a less harmful substance. Ecolochem offers a range of oxygen scavengers tailored to specific water chemistries and application requirements. The selection process considers factors such as water pH, temperature, and the presence of other interfering ions. Common scavenger types include sulfites, hydrazines, and ascorbic acid, each with its own advantages and limitations regarding effectiveness, safety, and environmental impact. Precise dosing is critical for optimal efficiency and to avoid residual scavenger effects.
Membrane Technology: Membrane-based gas removal utilizes specialized membranes that selectively permeate dissolved gases while retaining water. This method offers high efficiency and a compact footprint. Ecolochem's membrane systems may incorporate hollow fiber or spiral-wound membranes, depending on the specific application requirements. The choice is influenced by factors like flow rate, gas concentration, and the required level of oxygen reduction. Membrane systems often require pre-treatment to prevent fouling and ensure long-term performance.
Degassing Columns: These columns utilize specialized packing materials to increase the contact area between water and air, facilitating gas stripping. The water flows counter-currently to an air stream, enhancing gas transfer. Ecolochem designs columns tailored to specific flow rates and gas removal targets, optimizing packing material type and column dimensions to maximize efficiency. The design considerations include the type and concentration of dissolved gases, water flow rate, and the required degree of gas removal.

Models range from smaller units suitable for localized applications to large-scale systems for industrial plants. Key design features include tray configuration (in tray-type models), spray nozzle design (in spray models), vacuum pump capacity (in vacuum models), and heat exchanger efficiency.
Chemical Treatment Models: These involve customized formulations of oxygen scavengers tailored to specific water chemistries and application requirements. The models differ in scavenger type and concentration, providing flexibility in addressing varying oxygen levels and water conditions. Model selection requires careful analysis of water quality parameters and process needs.
Membrane-based Models: These vary based on membrane type, membrane area, and overall system configuration. Factors influencing model selection include flow rate, desired gas removal efficiency, and the potential for membrane fouling. System design incorporates pre-treatment steps to mitigate fouling and enhance membrane lifespan.
Degassing Column Models: These models vary primarily in size and packing material, influencing capacity and efficiency. Design considerations include column diameter, height, packing type, and air flow rate. Model selection balances gas removal effectiveness with capital and operational costs.
