Procurement of Hydrated Lime (Calcium Hydroxide) often starts with specifying purity and physical form since these determine its suitability in applications such as water treatment or construction. Decision-makers in industries from municipal water plants to construction contractors seek a stable, consistent reagent to ensure process efficiency. Hydrated Lime, with the chemical formula Ca(OH)₂, is a white crystalline powder that serves a pivotal role in neutralizing acidic conditions, coagulating impurities, and stabilizing soils.
This product’s alkaline nature makes it indispensable in East African countries including Kenya, Uganda, Tanzania, and Rwanda, where it supports critical infrastructure projects and environmental management. Buyers rely on suppliers like Zenco Systems Ltd to deliver Hydrated Lime that meets stringent quality standards to maintain reliable operational results. Beyond water treatment, it is also specified for soil stabilization and as a key component in mortars and plasters within the construction sector, highlighting its commercial importance in the region’s industrial activities.
Hydrated Lime is chemically defined as Calcium Hydroxide, with the formula Ca(OH)₂ and a CAS number of 1305-62-0. It is manufactured by treating quicklime (Calcium Oxide) with water in a controlled slaking process, resulting in a fine, dry, white powder. The particle size and moisture content can influence its reactivity and handling characteristics. This chemical is moderately soluble in water, releasing hydroxide ions (OH⁻), which confer strong alkalinity to solutions typically with pH values between 12 and 13, depending on concentration.
The primary mechanism at work in water treatment is precipitation and neutralization. When added to acidic water or wastewater, Hydrated Lime raises pH levels and precipitates dissolved metals and suspended solids by forming insoluble compounds that can be filtered out. It is especially effective in removing hardness and heavy metals, improving water clarity and safety. In construction, its ability to bind with silicates stabilizes soils and enhances workability of mortars and plasters, improving durability and resistance to cracking.
Key properties that buyers monitor include purity, usually indicated by calcium hydroxide content, and absence of contaminants such as magnesium or unreacted lime. Particle size distribution impacts dispersion when used in slurries and also affects reactivity rate. The fine crystalline form supplied by Zenco Systems Ltd ensures consistent dosing and predictable performance in the demanding environments of East Africa. While technically classified under the water treatment chemicals category, Hydrated Lime’s versatility also extends to industrial pH adjustment and chemical reagent applications across multiple sectors.
Hydrated Lime is commonly dosed into raw water to raise pH and precipitate impurities like heavy metals and suspended solids. In municipal and industrial plants across Kenya, Uganda, and Tanzania, it helps reduce water hardness and improves coagulation efficiency. Typical usage involves slurry preparation with precise concentration control to optimize contaminant removal without overdosing, which can cause scaling.
In construction and civil engineering projects, Hydrated Lime is mixed with clay or silty soils to improve bearing capacity and reduce plasticity. Its alkaline nature alters soil chemistry by reacting with silicic acid and alumina, causing particle flocculation. This process is critical for road base preparation and foundation support in regions prone to soft or expansive soils.
Hydrated Lime serves as a key ingredient in traditional mortar and plaster formulations, improving workability, water retention, and bonding properties. It reacts chemically with carbon dioxide in the air over time, creating a harder, more durable surface. This application is particularly important in East African building contexts where cost-effective, long-lasting materials are essential.
Industrial processes frequently require pH control to maintain operational safety and product quality. Hydrated Lime is added in controlled amounts to neutralize acidic streams, especially in chemical manufacturing and wastewater treatment, ensuring regulatory compliance and protecting infrastructure from corrosion.
Beyond potable water, Hydrated Lime is vital in industrial wastewater management. Its addition precipitates heavy metals, reduces biological oxygen demand (BOD), and disinfects via alkalinity. This enables safer discharge or recycling of treated effluents, meeting environmental standards in the East African region.

Hydrated Lime’s strong alkaline nature allows it to rapidly neutralize acidic conditions in water and soil, stabilizing pH within target ranges. This control prevents corrosion damage in pipes and equipment, making it key to protecting infrastructure in water and wastewater setups.
By enhancing coagulation in water treatment and promoting particle flocculation in soil stabilization, Hydrated Lime reduces chemical consumption downstream. This operational benefit translates directly to cost savings and more predictable results.
The chemical’s ability to serve diverse roles—from pH adjustment to construction binding agent—makes it a flexible input in procurement planning. Suppliers like Zenco Systems Ltd provide consistent quality to support multiple industries with one reliable product.
With low moisture content and controlled particle size, Hydrated Lime from trusted suppliers minimizes caking and dust generation. This property reduces handling risks and simplifies storage logistics in the tropical climates encountered in East Africa.
Hydrated Lime is supplied in 25kg and 50kg multi-wall bags suitable for manual handling by construction and water treatment firms. For larger industrial users, 200L drums offer convenient bulk storage and safer handling. Zenco Systems Ltd supports cross-border deliveries within Kenya, Uganda, Tanzania, and neighboring East African countries, ensuring packaging meets regional transport and storage conditions.

Store Hydrated Lime in a cool, dry environment away from moisture sources to prevent caking and premature carbonation. Packaging should remain sealed until use to maintain product quality. Avoid contact with acids or incompatible materials such as aluminum. Handling requires protective gloves and eye protection because of its alkaline nature, which can irritate skin and eyes. Shelf life under appropriate conditions typically extends up to 12 months, but best practice is to rotate stock to maintain freshness.
Hydrated Lime is caustic and can cause skin irritation or eye burns upon contact. Use appropriate personal protective equipment (PPE) such as gloves, goggles, and dust masks when handling or transferring. In case of exposure, rinse affected areas with plenty of water and seek medical attention if irritation persists. Avoid inhaling dust by working in well-ventilated areas. Dispose of waste following local regulations. Refer to the Safety Data Sheet (SDS) from Zenco Systems Ltd for comprehensive safety guidelines.
Hydrated Lime is used to increase pH and precipitate impurities such as heavy metals and suspended solids, improving water quality and making it safe for consumption or discharge.
Typical dosing ranges from 2% to 8% by weight of soil, depending on soil type and project specs. It’s mixed thoroughly to promote chemical reactions that improve soil strength.
