Waste Water Treatment
Anaerobic degradation can be accelerated and increased by prior homogenization or disintegration of secondary sludge.Homogenization is achieved by mechanical stress and with little energy input. Flocs are broken up, sludge viscosity is reduced and anaerobic degradation accelerated.
Disintegration is achieved by mechanical, acoustical (ultrasound) or thermal means. With higher energy input cells are broken up and their content is released. Some organic matter is hydrolyzed. Dyna-Ken Case Histories MATERIAL:Portland cement dispersed into waste water with hazardous components. Sodium silicate added to decrease solidification time. PROBLEM: Batch mixing of waste into Portland cement powder for solidification in 55 gallon drums is messy and waste splashes out of the drum. Full drums cannot be mixed since the mixing action will cause overflow. Any leakage of the liquid waste is a large problem. RESULTS: Portland cement was dispersed at 1 pound per gallon, 2 pounds per gallon and 3 pounds per gallon concentrations into water with sodium silicate. Hardening of the cement dispersion occurred in approximately 15-30 seconds. Hardening that prevented flow occurred almost immediately after dispersion exited Dispershear. Dyna-Ken Solutions: Model VT300 Dispershear in pilot laboratory and for full 55 gallon batch applications. EQUIPMENT REPLACED:No other equipment was ever able to successfully mix this quickly. BENEFITS:Instantly non-flowable solidified waste and 55 gallon drums can be filled to the very top. |
Wax Emulsions
Waxes and polishes emulsions encompass a range of products including solid car waxes, liquid waxes, and shoe polishes. The manufacturing process for these products generally includes melting a solid wax, adding any suspending agents or minor ingredients, emulsifying the liquid wax with either a water or oil phase, cooling the product, and packaging.
Dyna-Ken Case Histories OBJECT: Provide improved dispersion in less time. Consisted of Part A: Mineral spirits, melted wax and additives. Part B: Water and pigments. PROBLEM: Provide total mix that will not separate. A to B ratio approximately 1:1. RESULT: Emulsified/Dispersed above without any separation. Dyna-Ken Solutions: BT200-03 batch homogenizer with 3 HP motor. EQUIPMENT REPLACED: Lightnin agitator. |
Toothpaste
Toothpaste is a common household item that most of us take for granted. However, the manufacturing process holds a number of challenges for processors. Toothpaste is manufactured by dispersing various solids into an aqueous base. The solids include thickeners (i.e. CMC, cellulose, xanthan gum, etc.), abrasives (i.e. silica), flavors, coloring agents, and other ingredients (i.e. fluoride). Traditional mixing techniques result in long blend times, lumps or agglomerates in the product, unstable product (phase separation), and wasted raw materials.
Dyna-Ken Case Histories MATERIAL: Dispersion of: abrasives, titanium dioxide, flavoring, cleaning agents, active ingredients and gelling agents. PROBLEM: Batch mixing equipment leaves 1/8" lumps of dry ingredients. In-line delumping equipment allows specks to pass through. RESULTS: Excellent de-lumping performed continuously at 40 gpm. Dyna-Ken Solutions: Model VT300, toothed impeller/liner, 7.5 HP, 360-3600 RPM, 1/16" grid (pilot plant). Model VT300, toothed impeller/liner, 15 HP, 1800 RPM, 1/16" grid (production facility). EQUIPMENT REPLACED: High speed pipe-line mixer to deaerator. BENEFITS: Ensured product quality at high production rates. No overshearing or aeration. |
